What happens when you mix Sodium hydroxide and phenolphthalein?
When you mix sodium hydroxide and phenolphthalein, you will observe a color change. Phenolphthalein is commonly used as a pH indicator, turning pink in basic solutions (such as sodium hydroxide) and colorless in acidic solutions. This color change is a result of the chemical reaction between the sodium hydroxide and phenolphthalein molecules.
What happens when you mix calcium hydroxide and phenolphthalein?
When you mix calcium hydroxide and phenolphthalein, the solution will turn pink or magenta in color. This color change indicates that the solution is basic, as calcium hydroxide is a strong base. Phenolphthalein is a pH indicator that changes color in the presence of bases.
Why phenolphthalein is chosen as the suitable indicator for sodium hydroxide?
Phenolphthalein is chosen as a suitable indicator for sodium hydroxide because its color change occurs in the pH range around 8.2 to 10.0, which is close to the pH range of the equivalence point for the titration of a strong base like sodium hydroxide with a strong acid. This allows for a sharp and easily detectable color change at the endpoint of the titration.
What happens when sodium hydroxide is added dropwise to solution containg phenolphthalein?
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will gradually turn pink as the pH increases. This color change is due to the phenolphthalein molecule shifting from its colorless form in acidic conditions to its pink form in basic conditions.
What is the evidence for a shift in equilbrium when ammonium chloride was added to the stock solution in hydroxide phenolphthalein?
What is the evidence for a shift in equilibrium's when ammonium chloride was added to the stock solution in hydroxide phenolphthalein? In: http://wiki.answers.com/Q/FAQ/2455 [Edit categories]

Is phenolphthalein a chemical property or a physical property?
Phenolphthalein itself is a chemical. It changing color is a chemical change.
What colo is PHTH in Sodium Hydroxide?
Phenolphthalein turns pink in basic solutions
What happens when you mix calcium hydroxide and phenolphthalein?
When you mix calcium hydroxide and phenolphthalein, the solution will turn pink or magenta in color. This color change indicates that the solution is basic, as calcium hydroxide is a strong base. Phenolphthalein is a pH indicator that changes color in the presence of bases.
Why phenolphthalein get colour on basic medium?
Phenolphthalein is colorless in acidic solutions but turns pink or purple in basic solutions because the hydroxide ions in the basic medium react with phenolphthalein to form a pink-colored compound. This color change is due to a shift in the chemical structure of phenolphthalein when exposed to a basic environment.
Is there a reaction between the ammonium hydroxide inside a plastic bag when immersed in a water with phenolphthalein?
If the phenolphthalein solution turns pink, that means that the plastic bag is permeable to ammonium hydroxide. If it remains colorless, then the plastic bag is not permeable to ammonium hydroxide. If the contents of the plastic bag turn pink, then the plastic bag is permeable to phenolphthalein. If everything remains colorless, then the bag is impermeable to both ammonium hydroxide and phenolphthalein.
Why does Phenolphthalein turn pink in potassium hydroxide solution?
Oh, dude, it's like this chemical reaction party where Phenolphthalein gets all excited and turns pink when it hangs out with potassium hydroxide. It's because the potassium hydroxide is a strong base that steals hydrogen ions from the Phenolphthalein, making it change color. So yeah, it's just chemistry being all colorful and stuff.
What happens with phenothalein is placed in Magnesium hydroxide?
Phenolphthalein in a solution containing magnesium hydroxide would remain colorless as it does not change color at a basic pH, where magnesium hydroxide is present. Phenolphthalein changes color in acidic solutions, not basic ones.
Is adding lime to baking soda a chemical change?
Yes, adding lime (calcium hydroxide) to baking soda (sodium bicarbonate) results in a chemical change known as a double displacement reaction. The reaction forms water, sodium hydroxide, and calcium carbonate.
Is hydrochloric acid and phenolphthalein a chemical change?
When HCl and phenolphthalein are mixed, a chemical reaction occurs leading to a change in the color of the solution (from pink to colorless). This is a chemical change as new substances are formed with different properties than the original substances.
In an ammonia stock with phenolphthalein solution would the sodium hydroxide tend to decrease the color intensity?
Yes, sodium hydroxide would tend to decrease the color intensity of the phenolphthalein solution in an ammonia stock. Sodium hydroxide is a strong base that would react with phenolphthalein, causing it to change color from pink to colorless.
What happen when sodium hydroxide is added drop wise to a solution containing phenolphthalein?
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will initially remain colorless. Once enough sodium hydroxide has been added to make the solution basic, the color will change from colorless to pink or purple, indicating the presence of hydroxide ions. Phenolphthalein is a pH indicator that changes color in the presence of a base.
